On this page
The local server uses stdio. The remote app uses official SDK Streamable HTTP in stateless SSE response mode. All advisory text is untrusted reference data.
Remote: content only, no filesystem paths and no AI tools. Body limit 2 MB; maximum 5,000 packages; 20-second timeout. Rate limit 30 requests/minute/IP/instance. These checks do not execute repository code.

explain_findings is registered only with your own provider keys. It enriches the last scan within that local session; neither findings nor verdict can change. Remote servers never register it.
